Frangible electronic label resistant to metal

Abstract

The invention discloses a frangible electronic label resistant to a metal. The frangible electronic label comprises a surface paper layer (4), a base plate (1), an ethylene Vinyl acetate copolymer (EVA) isolation layer (5), an aluminum layer (6) and a bottom paper layer (7) which are sequentially bonded from top to bottom, wherein the base plate (1) is made of a frangible film; a signal circuit (2) and a chip (3) are arranged on the lower surface of the base plate (1); multiple groups of tool marks are arranged on the EVA isolation layer (5) and the aluminum layer (6) and penetrate through the EVA isolation layer (5) and the aluminum layer (6); each group of tool marks comprises two tool marks (8) arranged on the same straight line; a region encircled by connecting the EVA isolation layer (5) and the aluminum layer (6) into a circle in a head-to-tail manner by the multiple groups of tool marks forms a region easy to separate (10); and the chip (3) and a small part of signal circuit (2) are bonded with the region easy to separate (10). The label is isolated from metal interference, and can be effectively prevented from being reused by a lawless person.

Description

technical field [0001] The invention relates to the technical field of radio frequency identification, in particular to a fragile anti-metal electronic tag. Background technique [0002] Electronic tags are also called radio frequency tags, transponders, and data carriers; readers are also called readout devices, scanners, reading heads, communicators, and readers (depending on whether the electronic tags can rewrite data wirelessly). The contactless coupling of radio frequency signals is realized between the electronic tag and the reader through the coupling element, and in the coupling channel, energy transmission and data exchange are realized according to the timing relationship. People affix the radio frequency tag on the metal as a metal tag, and use the tag's chip to read and write information about the metal's composition type, manufacturer, sales channel, etc., for easy management. [0003] Metal tags in the prior art generally include a substrate, a signal circuit...

AI Technical Summary

Problems solved by technology

The metal tag of the prior art has the following defects: the chip and the complete signal circuit of the metal tag are integrally pasted on the PET substrate, and can be peeled off without damaging the metal tag. In this way, the metal tag can still be used without damage. It affects the normal function of sending and receiving signals. Therefore, a small number of criminals take advantage of this loophole to easily replace or reuse metal tags. Torn off and pasted on another or counterfeit and inferior metal will confuse information and endanger product safety, so the metal label can be easily removed and reused, which obviously violates the original intention of using the metal label
